I believe Saaz is a German name for a Czech town named Žatec. The Czechs call the hops from this town "Žatecki". Saaz would be pronanced "Sahz'', Žatec is pronanced "Zsatetz" ("Zs" like in "Zsa Zsa Gabor"), and Žatecki is pronounced "Zsatetzky", (again, "Zs" like in "Zsa Zsa Gabor").http://cs.wikipedia.org/wiki/%C5%BDatec

yeah, they call the symbol a hacek (by the way the c in hacek should also have a hacek above it, I don't know my international keyboard codes :P ) Usually the hacek changes a hard consonant to a soft consonant.
Hacek = HA-chek

Yeah, it's the same as here then. We have Ž, like the S in pleasure, Š, like SH, Č and Ć which are a hard and soft CH sound and Đ, like the G in George. And the C here is also like TS.

I have seen the Czech beer Krušovice here, for instance, and that is pronounced KrooShoVeetsEh with a rolled R.
